What trans should I run?

I have a 400+ hp 360 with a 727, 2800 converter, turbo action full manual valve body, B&M ratchet shifter, 8 3/4 3.91 suregrip.

A buddy of mine located a a833 4 speed from a 68 dart 318 car. The guy wanted $400 for what I thought was everything. Turns out 400 bought the just the trans. With the bell housing, flywheel, linkage, z bar, pedals looking closer to 700. The trans worked when it was parked. What would have to be done to make it hold up?
